They're complaining that Go doesn't even reflect the state-of-the-art of 30 years ago.
Clearly that was a very deliberate choice on the part of the Go creators, not the result of oversight or ignorance. I suspect they simply didn't want to reflect the state of the art 30 years ago, 20 years ago, or today. I don't find that at all surprising, because people who want to get things done often like very simple tools which stay out of the way. To each their own though, and I'm sure the go creators would be very happy to see other languages used instead of go by those who prefer more features, more complexity, state of the art from 30 years ago, etc. I do find myself puzzled by the hostility it generates though - it is just a language, one of many, and about which some very ordinary claims are being made (easy to learn etc).
